MEANS FOR SINKING PIPES AND FACING PLATES.

Application filed October 7, 1925.

This invention relates to an improved means for sinking pipes and facing plates for use in lining shafts, and other excavations, either vertical, horizontal or inclined, and more particularly relates to such a means which is an improvement over the form shown in my U. S. Patents No. 1,202,- 5 15 and No. 1,008,727.

A particular object of this Invention is to provide means adapted to be secured to the lower end of the tube or pipe or adjacent the lower edge of the facing plate adapted to receive the blow or impact of the hammer or other means provided for sinking or driving the pipe or plate into the ground, thereby eliminating the usual danger of buckling or damaging the upper end of the pipe or facing plate when the blow is applied directly thereto as is now common practice.

Other objects of the invention will appear from the following description and the accompanying drawings and will be pointed out in the annexed claims.

In the drawings there has been disclosed a structure designed to carry out the various objects of the invention but it is to be understood that the invention is not confined to the exact features shown as various changes may be made within the scope of the claims which follow.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings formingpart of this specification v Figure 1 is a perspective sectional view showing a pipe or tube partially driven into the ground and also showing the shoe secured to the lower end thereof adapted to receive the blow of the hammer;

Figure 2' is a detail view showing the shoe removed from the tube;

Figure 3 is a detail sectional view through the lower portion of the shoe;

Figure 1 is a detail view of the tube or pipe with the shoe removed therefrom;

Figure 5' is a modified constructlon showing a shoe secured to the bottom of a pipe or tube and having the driving means arranged outside of' the tube; I

the preferred manner of driving or sinking a facing plate into the ground; and

Figure 8 is a detail sectional view showing how the drive pipe or tube is demountably connected to the facing plate.

In the selected embodiment of the invention as shown, there is illustrated in Figure 1, a hollow pipe or tube 11 havin a reinforcing or driving shoe 12 secure to the lower end-portion thereof by such means as rivets 13. The inside diameter of the driving shoe 12 is preferably of suitable size to receive the lower end of the pipe 11 so that when thelatter is sunk into the ground the hole provided by the shoe will be relatively larger than the diameter of the pipe to prevent the walls of the pipe from frictionally engaging the walls of the hole. The lower edge 1 1 of the shoe 12 is preferably sharpened as shown in Figure 1 in order to more readily cut through the earth.

A series of lugs or brackets 15 are securely riveted or fastened to the lower portion of the driving shoe adjacent the cutting edge 14. Each lug 15' has a pin 16 mounted therein adapted to receive the lower end of a driving pipe or stem 17 which extends upwardly through the pipe 11 and has its upper end-portion projecting above the top of the pipe as shown in Figure 1. A suitable cap 18 is preferably mounted upon the driving stem 17 to reinforce its upper end and receive the blow of the hammer and prevent the upper end of the stem from buckling or being damaged when the shoe is driven into the earth. A guide 19' may be secured to the upper end of the pipe 11 to provide meansfor retaining the stem 17 in an upright position. This guide, however, may be eliminated if desired and especially if the pipe 11 is relatively long.

In sinking the pipe or tube 11 into the earth the shoe 12 will be suitably secured to the lower end portion thereof as shown in Figure 1, after which it will be arranged in an upright position upon the ground and the driving stem 17 mounted thereinwith its lower end seated upon one of the lugs 15 as shown. The shoe 12. and thereforethe pipe 11, may then be driven into the earth by applying the blow of a hammer or other 'drivin means to the upper face of the cap 18. The blow or impact of the hammer to the cap 18 will be transmitted throu h the driving tube or pipe 17 to the-lugs 15 secured 11 and also preventing it from being dainaged while being sunk into the earth.

Figures 5 and 6 illustrate modified construction wherein the driving shoe 21 is constructed of two plates suitably formed and riveted or secured together so as to receive the lower end of the tube or pipe 11 as shown particularly in Figure 5. The pipe 11 is provided with suitable apertures 22 as shown in Figure 4;, adapted to receive the rivets 13 for securing-the shoe thereto. Upwardly extending lugs or projections 23 are preferably integrally formed upon the upper edges of the opposed flanges 2 1 of each half of the driving shoe 21, which halves are securely riveted together by means of rivets 25 as shown. The lugs 23 provide means for receiving the lower end of the driving tube 17 and function in a manner similar to the pins 16 shown and described with reference to the previous figures. In the construction here shown, the driving force is applied to the outside of the tube 11 instead of to the inside as shown in Figures 1. 2 and 3, thereby leaving the interior of the pipe 11 unobstructed for the removal of the earth.

Figures 7 and 8 illustrate another construction wherein the drive tubes 17 and lugs 15 are shown connected to a straight facing plate 26 so that it likewise may be driven into the earth by applying the force of the blow to the lower edge instead of to the upper edge thereof, now common practice when sinking facing plates and shaft linings into the earth. The guides 19 are also shown secured to the upper portion of the plate 26 to provide means for retaining the driving stems in an upright position as shown. The facing plate 26 also preferably has its lower edge 27 sharpened to more readily cut through the earth.

From the foregoing, it will readily be seen that by the employment of the driving shoes 12 or 21 in connection with the pipe or tube 11 the latter may readily be driven into the earth without danger of buckling or damaging the upper portion or end thereof. Two or more lugs 15 are preferably provided upon the lower end of the shoe 12 and a driving tube is provided for each lug so that no shifting of the driving pipes or tubes is necessary in the operation of forcing the pipes in the ground.

The lugs 15 and driving tubes 17 may also be used in driving facing plates into the earth to provide means for lining a shaft or other excavation. When thus lining the walls of a shaft or excavation by driving the facing plates into the earth, such plates mustobviously be suitably braced or secured together by means, not shown, before the earth confined within the walls thereof is removed. As the particular construction or method employed for securing together the facing plates, when driven into the earth, forms no part of the present invention, it is thought unnecessary to show same in the drawings.

It will be understood that as the shoe 12 and the pipe 11 are driven into the ground that additional length of pipe will be placed upon the pipe 11 and the length of the pipe 17 will be correspondingly increased as the shoe 12 is driven into the coil until the desired depth is reached. WVhen a straight facing plate is used instead of a pipe with a cylindrical shoe, additional plates will be placed upon the lower one as it is driven into the ground and the length of the pipes to which the driving force is directly applied will also be increased.

I claim as my invention:

1. The combination with a hollow post, of spaced abutments secured to the lower portion of the post, a blow-transmitting device seatable upon any abutment and adapted to project above the post when so seated.

2. The combination with a post, a cutting shoe encircling and secured to the bottom of the post and having a cutting edge at its bottom said shoe having spaced abutments, and an elongated blow-transmitting member seatable upon an abutment and when so seated adapted to project above the post.

3. The combination with a pipe, of a shoe secured to the lower portion thereof and having a cutting edge, lugs secured to said shoe, a pipe adapted to be seated on one of said lugs and projecting upwardly therefrom to receive the blow of a driving means, said pipe and lug transmitting the force of such blow to said shoe.

1-. A hollow post, a plurality of spaced ledges attached to the post adjacent its lower end, and a pipe engageablewith any ledge and extending above the top of the post, each ledge having an upwardly extending pin adapted to receive the pipe to hold its lower end against slippage.

5. A hollow post having spaced abutments adjacent its lower end each abutment having a vertically arranged pin, and a pipe engageable over any pin, and when so engaged adapted to extend above the post.

6. A hollow post having a cutting shoe encircling the same at its lower end and extending outwardly therebeyond, said shoe having a series of spaced abutments circularly arranged thereon, and a driving stem having its lower end engageable with any abutment, and when so engaged adapted to have its upper end projecting above the post.

7. A hollow post having a cutting shoe encircling the same at its lower end, said shoe comprising two sections secured together, each section having an extension and the extensions arranged to reinforce one another when the sections are connected in 139 resting upon the abutment, in amanner to prevent jumping off during the pounding operation, whereby the driving rod can be disengaged from or engaged over the projection of any abutment, the arrangement being such that the driving force can be applied successively or alternately at a number of points.

In Witness whereof, I have hereunto set 20 my hand this 80th day of September, 1925.

WILLIAM T. MCCARTHY.
